An electric heater operating at 120. volts draws

8.00 amperes of current through its 15.0 ohms of

resistance. The total amount of heat energy

produced by the heater in 60.0 seconds is

(1) 7.20 * 10^3 J (3) 8.64 * 10^4 J

(2) 5.76 * 10^4 J (4) 6.91 * 10^6 J

    Ohms law says that V = IR

    The amount of work done is P = IV or P = I^2R (using Ohm's law to substitute)

    Therefore P = 64*15 = 960W

    So the total energy released is Pt = 960*60 = 57600J
